Abstract

En fysiologisk sensoranordning omfatter en elektrisk sensor (4) for innføring i vevet til et levende dyr, og som måler partialtrykket for karbondioksid i dyrevevet. Anordningen innbefatter også en elektrisk kabel (6) elektrisk forbundet ved sin distale ende til sensoren (4). Kabelen (6) er omgitt av en kappe (28). Kappen (28) har flere fleksible partier (30) atskilt med langsgående slisser (29). Bevegelse av den proksimale ende av kappen (28) mot den distale ende, minsker avstanden mellom endene til de fleksible partiene (30) og får dem til å bøye seg utover. Sensoren (4) kan holdes på plass i dyrevevet av de utbøyde, fleksible partiene (30).A physiological sensor device comprises an electrical sensor (4) for introduction into the tissue of a living animal, and which measures the partial pressure of carbon dioxide in the animal tissue. The device also includes an electrical cable (6) electrically connected at its distal end to the sensor (4). The cable (6) is surrounded by a sheath (28). The sheath (28) has several flexible portions (30) separated by longitudinal slots (29). Movement of the proximal end of the sheath (28) toward the distal end reduces the distance between the ends of the flexible portions (30) and causes them to bend outward. The sensor (4) can be held in place in the animal tissue by the bent, flexible portions (30).
